Foods to Eat During Your Third Trimester

The growth and development of your baby will depend on what you eat, and that’s the reason why the 7 to 9 months pregnancy diet is crucial. You will now need about 200 additional calories every day, and an adequate quantity of vitamins, fibre and minerals. Here is what you should include in your pregnancy diet.

Healthy fruits and vegetables

1. Foods Rich in Iron
A diet that lacks iron could lead to anaemia during pregnancy, which can make you dizzy and tired. It may also cause bleeding during delivery. Hence, eating iron-rich foods is necessary. In your last trimester pregnancy diet, you can include meat, dairy products, eggs, wheat bran and beans.

2. Foods Rich in Protein
Your body will need about 70 grams of protein during this stage since it helps in the formation of the baby’s body. Eating protein-rich foods will ensure that your blood glucose levels remain constant and the risk of diabetes is minimised. You can eat foods like tofu, legumes, fish, and meat. 

3. Foods Rich in DHA
Having DHA-rich foods during pregnancy can help develop the baby’s brain. You will need about 200 milligrams of DHA (docosahexaenoic acid
) daily and to meet these requirements you can include milk, eggs, and fruits in your meals.

4. Foods Rich in Folic Acid
Folic acid is found in green leafy vegetables like spinach and romaine lettuce – you can include these in your third-trimester diet. Consuming folic-acid rich foods will ensure proper foetal growth and lower the risk of low-birth-weight of your baby. Apart from eating spinach and lettuce, you can even include folic acid, beans, and citrus fruits.

5. Foods Rich in Calcium
In the third trimester of your pregnancy, your baby’s bones should get stronger and for that, your pregnancy diet should include about 800 mg of calcium. To meet your calcium requirements, you can add and milk products like cheese, tofu, and yoghurt to your diet. Salmon and nuts are also good sources of calcium. However, if you plan to eat salmon, first, check with your doctor if you can eat it or not. If she gives a go-ahead, make sure you cook it well before eating.

6. Foods Rich in Magnesium
Your body will need magnesium as it helps absorb calcium and repairs damaged body tissues, so you must include magnesium-rich foods in your diet. For 350 to 400 mg of magnesium, you can include almonds, pumpkin seeds, barley, oats, beans and artichokes to your diet. Eating these foods will also provide relief from muscle cramps and lower the risk of preterm labour.

7. Foods Rich in Vitamin C, B6 and B12
These vitamins play a significant role in the development of a baby through the musculature and placental growth. These vitamins can be found in oranges, bananas, sweet lime, carrots, chickpeas, and almonds.

8. Fruits and Vegetables
Eating fruits and vegetables is also important during pregnancy as they can provide you with various nutrients. Fibre-rich fruits and veggies can provide relief from constipation and regulate digestion. You can have them in the form of juices, smoothies or raw, fresh, frozen or canned.

9. Nuts
Nuts are a good source of protein, thiamine, and essential omega-3 fatty acids. If you do not feel up for lunch or dinner, grab a handful of almonds, walnuts, or pistachios and enjoy.

And if you are looking for foods to increase weight in the third trimester, you should eat more frequently and include foods that are nutrient and calorie-dense like dry fruits, nuts, and crackers with peanut butter.
